‘Retune the brain’ to stop tinnitus

In their study on rodents,the scientists banished tinnitus by electrically stimulating vagus nerve — a large nerve running from the head and neck to the abdomen — at the same time as playing sounds tuned to specific frequencies,’The Daily Telegraph’ reported.

Treated rats showed responses that indicated the ringing in their ears had stopped. Animals that did not receive the therapy continued to display signs of tinnitus.

According to them,when the vagus nerve is stimulated it releases chemicals that open the brain circuitry to being rewired; playing the sounds at same time permanently undoes the original damage caused by the hearing loss.
